METHOD FOR DETERMINATION OF ATHLETE CARDIORESPIRATORY SYSTEM STATE COMPLIANCE WITH SELECTED SPORT Russian patent published in 2017 - IPC A61B5/205 

FIELD: medicine.

SUBSTANCE: minute respiratory volume is measured in the initial state and at the end of functional exertion with increasing inhalation hypercapnia at carbon dioxide content of 7.5 vol % in the inhaled air. Heart rate is measured n the initial state and at the end of functional exertion with increasing inhalation hypoxia at oxygen content of 11 vol % in the inhaled air. Chemoreactivity fitness index (CFI) of the cardiorespiratory system is calculated by the original formula. If the value of CFI is less than or equal to 40%, the conclusion is made on cardiorespiratory system state compliance with the sport types related to cyclical aerobic muscle activity, accompanied by willed breath delays. If the value of CIF is in the range of 40 to 60% inclusive, the conclusion is made on cardiorespiratory system state compliance with the sport types related to cyclical aerobic muscle activity without willed breath delays. If the value of CFI exceeds 60%, the conclusion is made on cardiorespiratory system state compliance with the sport types related to acyclical aerobic muscle activity with abrupt changes of power or speed load. If the CFI value of an athlete does not correspond to the muscle activity typical for the sport, he/she is engaged with, a conclusion is made on cardiorespiratory system state non-compliance with the selected sport type, it is recommended to select another sport type with CFI value closer to the individual CFI of this athlete.

EFFECT: method allows to determine the cardiorespiratory system state for sport types, detect non-compliance of the cardiorespiratory system state to the selected sport and to recommend the most suitable sport.
